Report #18058

[architecture] Agent cannot answer questions requiring connecting multiple distinct facts stored separately

Augment vector memory with a Knowledge Graph \(GraphRAG\) to store relationships \(triples\), allowing the agent to traverse edges \(e.g., User -> current\_project -> ProjectX, ProjectX -> manager -> Jane\).

Journey Context:
Vector stores excel at finding semantically similar text but fail at multi-hop relational queries. If facts are stored as separate chunks, vector search for a transitive relationship might only retrieve one. GraphRAG solves this by structuring data as entities and relations, enabling traversal. The tradeoff is significantly higher extraction complexity and maintenance of the graph schema compared to dumping text into a vector DB.
